Playing world sound

[Otacon]

Hey there, I want to change the darkRP lockdown to loop a sound as well as play a sound when it is initiated. Basically, the mayor initiates lockdown, an overwatch message is broadcasted, then for the duration of the lockdown, this specific sound is looped. Once the lockdown ends, the sound stops.
Code snippet:

local function Lockdown(ply)
	if not lstat and ply:Team() == TEAM_MAYOR then
		for k,v in pairs(player.GetAll()) do
			v:ConCommand("play npc/overwatch/cityvoice/f_confirmcivilstatus_1_spkr.wav\n")
		end
		lstat = true


		PrintMessageAll(HUD_PRINTTALK , LANGUAGE.lockdown_started)
		RunConsoleCommand("DarkRP_LockDown", 1)
		NotifyAll(4, 3, LANGUAGE.lockdown_started)
	end
	return ""
end

The sound I want to loop is: "ambient/alarms/citadel_alert_loop2.wav"

[lua]
local function Lockdown(ply)
if not lstat and ply:Team() == TEAM_MAYOR then
timer.Create( "lockdowntimer", 5, 0, function() // Change the value 5 to the number of seconds in between the sounds played
for k,v in pairs(player.GetAll()) do
v:ConCommand("play npc/overwatch/cityvoice/f_confirmcivilstatus_1_spkr.wav\n")
end
end)
lstat = true

PrintMessageAll(HUD_PRINTTALK , LANGUAGE.lockdown_started)
RunConsoleCommand("DarkRP_LockDown", 1)
NotifyAll(4, 3, LANGUAGE.lockdown_started)
end
return ""
end
[/lua]

IMPORTANT!!! You must put: [lua]timer.Destroy("lockdowntimer")[/lua] somewhere in the code that ends the lockdown, or the timer will be infinite

Thanks for the reply Andriko! I assume where you put function() in the timer.create you mean I should make a new function which simply plays the sound? For example:
local playlockdownFunction()
ConCommand("play ambient/alarms/citadel_alert_loop2.wav\n")
like that?

[Andriko1]

no, but what you could do is this:

[lua]
local function lockdowntimer()
for k,v in pairs(player.GetAll()) do
v:ConCommand("play npc/overwatch/cityvoice/f_confirmcivilstatus_1_spkr.wav\n")
end
end
timer.Create( "lockdowntimer", 5, 0, lockdowntimer )
[/lua]

My other version is just better
This also works with hook.Add(), concommand.Add(), and anything else where you input a function as an argument

[Otacon]

It is not liking the "pairs" value. "Bad Argument #1 'pairs' (table expected, got nil)"

EDIT: NEVERMIND! That error was from something else. I had a nil timer error but that was because I hadn't declared the function until after the lockdown function so I had to move my timer function above it, as you showed in your code snippet.
